Pediatric Trauma Anesthesia Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Pediatric Trauma Anesthesia. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Pediatric Trauma Anesthesia Indian Medical PG Question 1: A 40-year-old male with a head injury presents with a GCS of 8, BP of 90/60, and HR of 120. A CT scan shows an epidural hematoma. What are the immediate management priorities?
- A. Intubation and ventilation (Correct Answer)
- B. Administer mannitol for intracranial pressure management
- C. Perform immediate craniotomy
- D. Administer intravenous fluids and monitor vital signs
Pediatric Trauma Anesthesia Explanation: ***Intubation and ventilation***
- A GCS of 8 or less mandates **immediate intubation** to protect the airway and prevent aspiration in a patient who cannot maintain their airway.
- In the **ATLS primary survey sequence**, airway management is the first priority, though in practice this is done **simultaneously** with fluid resuscitation.
- Maintaining **adequate oxygenation and normocapnia** is crucial for preventing secondary brain injury and managing intracranial pressure.
- **Critical point**: While this patient requires both airway management AND fluid resuscitation urgently, securing the airway takes immediate precedence as the patient cannot protect their airway at GCS 8.
*Administer mannitol for intracranial pressure management*
- While mannitol can reduce ICP, it is **not an immediate priority** before securing airway, breathing, and circulation.
- Mannitol is **contraindicated in hypovolemic/hypotensive patients** as it acts as an osmotic diuretic and can worsen hypotension.
- ICP management with mannitol should only be considered after hemodynamic stabilization and in the context of signs of herniation.
*Perform immediate craniotomy*
- Although epidural hematomas typically require **urgent surgical evacuation**, the patient must first be physiologically stabilized.
- **No patient should go to the operating room in hemorrhagic shock** without ABC stabilization.
- Airway protection, ventilation, and circulatory resuscitation must precede definitive neurosurgical intervention to ensure the patient can safely tolerate anesthesia and surgery.
*Administer intravenous fluids and monitor vital signs*
- This is a **critical and equally urgent priority** - the patient is in shock (BP 90/60, HR 120), likely from associated injuries or blood loss.
- **Hypotension (SBP <90 mmHg) is the most detrimental secondary insult** in head-injured patients and doubles mortality (per Brain Trauma Foundation guidelines).
- Fluid resuscitation should begin **simultaneously** with airway management to restore cerebral perfusion pressure.
- However, in the ATLS sequence, airway (A) precedes circulation (C), making intubation the first listed priority, though both must be addressed concurrently in practice.
Pediatric Trauma Anesthesia Indian Medical PG Question 2: Which of the following is NOT included in the resuscitation of a neonate with HR < 60/min?
- A. Endotracheal tube intubation
- B. Chest compression
- C. Adrenaline
- D. None of the above (Correct Answer)
Pediatric Trauma Anesthesia Explanation: ***None of the above***
- All listed interventions—**endotracheal tube intubation**, **chest compressions**, and **adrenaline administration**—are standard components of neonatal resuscitation when the heart rate remains below 60 beats/min despite initial steps.
- This question asks which is *NOT* included, implying that all options are, in fact, appropriate interventions in this critical scenario.
*Endotracheal tube intubation*
- This is a critical step in **securing the airway** and ensuring effective positive pressure ventilation when other methods fail or prolonged mechanical ventilation is anticipated.
- It's indicated if the heart rate remains below 60 bpm despite adequate bag-mask ventilation and chest compressions.
*Chest compression*
- **Chest compressions** are initiated when the heart rate is less than 60 bpm *after* 30 seconds of effective positive pressure ventilation.
- They are used in conjunction with positive pressure ventilation to improve cardiac output and myocardial perfusion.
*Adrenaline*
- **Adrenaline** is administered if the heart rate remains below 60 bpm *despite* adequate ventilation and chest compressions.
- It acts as a potent **vasopressor** and **cardiac stimulant**, increasing heart rate and contractility.
Pediatric Trauma Anesthesia Indian Medical PG Question 3: Identify the instrument shown in the image:
- A. Nasogastric tube
- B. Uncuffed endotracheal (ET) tube (Correct Answer)
- C. Oropharyngeal tube
- D. Tracheostomy tube
Pediatric Trauma Anesthesia Explanation: ***Uncuffed endotracheal (ET) tube***
- This image displays a transparent, flexible tube with a distinct connector at one end and no inflated cuff near the distal tip, which is characteristic of an **uncuffed endotracheal tube**.
- Uncuffed ET tubes are commonly used in **pediatric patients** where a cuff could potentially damage the narrower, cone-shaped trachea.
*Nasogastric tube*
- A nasogastric tube typically has a much **smaller diameter** and a distinctly different tip design, often with multiple side ports for fluid aspiration or administration.
- It does not feature the large, universal connector seen on endotracheal tubes.
*Oropharyngeal tube*
- An oropharyngeal (Guedel) airway is a **rigid, curved device** inserted into the mouth to maintain an open airway, and it looks distinctly different from the flexible tube shown.
- It does not extend into the trachea like an ET tube.
*Tracheostomy tube*
- A tracheostomy tube is typically shorter, often with a curved neck flange for securement to the neck, and frequently made with an outer and inner cannula, which are absent in the image.
- While it helps maintain an airway, its design is specific for insertion directly into a tracheostomy stoma, unlike the longer tube for oral/nasal intubation.
Pediatric Trauma Anesthesia Indian Medical PG Question 4: A 25-year-old man is brought to the emergency department by ambulance after falling 20 ft from a ladder. He was placed on a backboard for spinal stabilization. Intravenous access was obtained en route, and he received infusion of crystalloids. The patient is unconscious upon arrival. His blood pressure is 91/44 mm Hg, pulse is 129/min, and respirations are 8/min. Pulse oximetry is at 85%. Evaluation shows several superficial facial lacerations, a depressed temporal skull fracture, and a forearm fracture. There are no periorbital or periauricular hematomas, and there is no significant neck edema. Which of the following is the most appropriate next step in management of this patient?
- A. Nasotracheal intubation
- B. Orotracheal intubation (Correct Answer)
- C. Needle cricothyroidotomy
- D. Laryngeal mask placement
Pediatric Trauma Anesthesia Explanation: ***Orotracheal intubation***
- This patient is **unconscious**, has a traumatic brain injury (depressed temporal skull fracture), and is experiencing **respiratory depression** (respirations 8/min, SpO2 85%). This indicates a need for **definitive airway management**.
- **Orotracheal intubation** using an **RSI (rapid sequence intubation)** approach with **manual in-line stabilization** of the cervical spine is the preferred method for airway control in trauma patients with suspected cervical spine injury.
*Nasotracheal intubation*
- This method is **contraindicated** in patients with suspected **basilar skull fracture** or **midface trauma**, which is a concern given the depressed temporal skull fracture.
- It also carries a higher risk of **epistaxis** and can be more difficult to perform in an emergency setting.
*Needle cricothyroidotomy*
- This is primarily used as a **rescue airway** when intubation is impossible or has failed (a "cannot ventilate, cannot intubate" scenario).
- While it provides an airway, it is not the **definitive method of choice** when orotracheal intubation is feasible.
*Laryngeal mask placement*
- A laryngeal mask airway (LMA) is a **supraglottic airway device** that does not protect the airway from aspiration as effectively as an endotracheal tube.
- It is generally not recommended for patients with **head trauma** or those at high risk of aspiration, and it is not a definitive airway solution for prolonged ventilation.
Pediatric Trauma Anesthesia Indian Medical PG Question 5: A child with moderate to severe head injury is admitted in PICU. First line treatments are all except:
- A. Analgesia and sedation
- B. Hypothermia
- C. Controlled mechanical ventilation
- D. IV mannitol (Correct Answer)
Pediatric Trauma Anesthesia Explanation: ***IV mannitol***
- While **intravenous mannitol** is used in the management of head injury to reduce **intracranial pressure (ICP)**, it is **not a first-line treatment**.
- It is a **second-line therapy** reserved for documented or suspected elevated ICP despite initial supportive measures.
- First-line management focuses on maintaining adequate oxygenation, ventilation, and cerebral perfusion, while mannitol is used for specific ICP management when needed.
*Analgesia and sedation*
- **Analgesia and sedation** are essential **first-line treatments** to reduce pain, anxiety, and agitation, which can increase **intracranial pressure (ICP)**.
- These therapies ensure patient comfort, decrease metabolic demand, facilitate mechanical ventilation, and prevent secondary brain injury.
*Hypothermia*
- **Therapeutic hypothermia** is **NOT routinely recommended** as a first-line treatment in pediatric traumatic brain injury.
- Current evidence (including the Cool Kids trial) has not demonstrated benefit, and it may be associated with adverse effects.
- It is considered **investigational** and not part of standard first-line management protocols.
- **Note**: While this is also not first-line, the question specifically tests knowledge that mannitol is second-line therapy for ICP management.
*Controlled mechanical ventilation*
- **Controlled mechanical ventilation** is a fundamental **first-line treatment** for severe head injury to secure the airway and ensure adequate oxygenation and ventilation.
- Prevents secondary brain injury from **hypoxia** and **hypercapnia**, which can worsen outcomes.
- Maintaining appropriate **PaCO2 levels** is critical to control cerebral blood flow and intracranial pressure.
Pediatric Trauma Anesthesia Indian Medical PG Question 6: What is the correct sequence of management in a patient who presents to the casualty with an RTA?
1. Cervical spine stabilization
2. Intubation
3. IV cannulation
4. CECT
- A. 2,1,4,3
- B. 1,3,2,4
- C. 2,1,3,4
- D. 1,2,3,4 (Correct Answer)
Pediatric Trauma Anesthesia Explanation: ***1,2,3,4***
- This sequence follows the **ATLS (Advanced Trauma Life Support)** protocol, prioritizing immediate life threats in order.
- **Cervical spine stabilization** is the **first action upon patient contact** to prevent secondary neurological injury in any trauma patient.
- **Airway management (intubation)** is then performed **with maintained in-line c-spine stabilization** - these occur nearly simultaneously but c-spine protection is instituted first.
- **IV cannulation (circulation)** follows to establish vascular access for resuscitation and medications.
- **CECT (imaging)** is performed last, once the patient is stabilized after addressing immediate life threats.
- This follows the **ATLS Primary Survey: Airway (with c-spine protection) → Breathing → Circulation → Disability → Exposure**.
*2,1,4,3*
- This incorrectly places intubation **before** cervical spine stabilization is initiated.
- In ATLS, **c-spine protection must be applied immediately upon patient contact** before any airway manipulation.
- Delaying IV cannulation until after CECT is inappropriate as circulatory access is critical for early resuscitation.
*1,3,2,4*
- While this correctly starts with cervical spine stabilization, it incorrectly places **IV cannulation before intubation**.
- In the ATLS primary survey, **Airway comes before Circulation** - securing the airway takes priority over establishing IV access.
- This sequence could delay critical airway management in a patient with respiratory compromise.
*2,1,3,4*
- This sequence places **intubation before cervical spine stabilization**, which violates ATLS principles.
- **C-spine stabilization must be the first action** upon approaching any trauma patient to prevent secondary spinal cord injury.
- While intubation with in-line stabilization is possible, the c-spine protection must be instituted first, not after beginning airway manipulation.
Pediatric Trauma Anesthesia Indian Medical PG Question 7: All are used in the management of head injury patient except?
- A. Neuromuscular paralysis
- B. Norepinephrine
- C. Glucocorticoids (Correct Answer)
- D. Sedation
Pediatric Trauma Anesthesia Explanation: ***Glucocorticoids***
- **Glucocorticoids** are generally **not recommended** for the routine management of head injury patients due to a lack of proven benefit and potential for harm.
- Studies have shown that their use in **traumatic brain injury (TBI)** can be associated with increased mortality and other adverse outcomes.
*Neuromuscular paralysis*
- **Neuromuscular paralysis** (e.g., with vecuronium or cisatracurium) is often used in severe head injury to facilitate **endotracheal intubation**, control intractable intracranial pressure (ICP), or prevent self-extubation.
- It helps in reducing metabolic demands and ensuring proper ventilation and oxygenation in critically ill patients.
*Norepinephrine*
- **Norepinephrine** is a potent **vasopressor** frequently used to maintain adequate cerebral perfusion pressure (CPP) by increasing mean arterial pressure (MAP) in head injury patients.
- Maintaining **CPP** is crucial to prevent secondary brain injury from ischemia.
*Sedation*
- **Sedation** (e.g., with propofol or midazolam) is essential in head injury management to reduce **agitation**, prevent increases in ICP, and facilitate mechanical ventilation.
- It helps in patient comfort and ensures stability of vital signs and neurological parameters.
Pediatric Trauma Anesthesia Indian Medical PG Question 8: A 60-year-old man underwent cardiac bypass surgery 2 days ago. He has now started forgetting things and is unable to recall names and phone numbers of his relatives. What is the probable diagnosis?
- A. Cognitive dysfunction (Correct Answer)
- B. Alzheimer's disease
- C. Post traumatic psychosis
- D. Depression
Pediatric Trauma Anesthesia Explanation: ***Cognitive dysfunction***
- **Postoperative cognitive dysfunction (POCD)** is a common complication after cardiac surgery, especially in older patients, marked by memory impairment and difficulty with concentration.
- The onset of **forgetfulness** and inability to recall names and phone numbers within days of cardiac bypass surgery is highly suggestive of POCD.
*Alzheimer's disease*
- Alzheimer's is a **neurodegenerative disease** with a gradual onset, characterized by progressive cognitive decline over months to years [1], not sudden changes post-surgery.
- While age is a risk factor, the acute presentation immediately following an operation makes Alzheimer's less likely as the primary cause [2].
*Post traumatic psychosis*
- Post-traumatic psychosis typically occurs after a severe traumatic event and involves symptoms like **hallucinations, delusions, and disorganized thinking**, which are not described in this patient.
- The patient's symptoms are focused on **memory and recall deficits**, not florid psychotic symptoms.
*Depression*
- Depression can cause cognitive symptoms like **poor concentration and memory problems**, often referred to as "pseudodementia."
- However, the abrupt onset specifically linked to surgery, without other prominent depressive symptoms like low mood, anhedonia, or sleep disturbances, makes depression less likely as the sole immediate cause.
Pediatric Trauma Anesthesia Indian Medical PG Question 9: Which of the following is the induction anesthesia of choice in the pediatric age group?
- A. A. Sevoflurane (Correct Answer)
- B. B. Desflurane
- C. C. Halothane
- D. D. Isoflurane
Pediatric Trauma Anesthesia Explanation: ***A. Sevoflurane***
- **Sevoflurane** is an inhalation anesthetic widely preferred for **pediatric induction** due to its rapid onset and non-pungent odor, which makes it well-tolerated by children.
- Its low blood-gas partition coefficient allows for swift changes in anesthetic depth and rapid emergence.
*B. Desflurane*
- **Desflurane** has a **pungent odor** and is known to cause airway irritation, making it unsuitable for inhalational induction in children.
- Its rapid onset and offset are beneficial, but its irritant properties limit its use for induction, especially in younger patients.
*C. Halothane*
- **Halothane** was previously used for pediatric induction but has largely been replaced due to its association with **hepatotoxicity** and cardiac arrhythmias.
- It also has a slower onset and offset compared to newer agents like sevoflurane.
*D. Isoflurane*
- **Isoflurane** has a **pungent odor** and can cause airway irritation, making it less suitable for inhalational induction in children compared to sevoflurane.
- While effective for maintenance, its irritant properties make for a less smooth and potentially distressing induction experience for pediatric patients.
Pediatric Trauma Anesthesia Indian Medical PG Question 10: What is the primary purpose of Sellick's maneuver?
- A. Prevention of hypertension
- B. Prevention of alveolar collapse
- C. Prevention of aspiration of gastric contents (Correct Answer)
- D. Prevention of bradycardia
Pediatric Trauma Anesthesia Explanation: ***Prevention of aspiration of gastric contents***
- **Sellick's maneuver**, also known as **cricoid pressure**, involves applying pressure to the cricoid cartilage.
- This pressure occludes the **esophagus**, thereby preventing the regurgitation and aspiration of gastric contents into the airway, especially during rapid sequence intubation.
*Prevention of alveolar collapse*
- **Alveolar collapse** (atelectasis) is typically prevented by maintaining positive end-expiratory pressure (PEEP) or using lung recruitment maneuvers during mechanical ventilation.
- Sellick's maneuver has no direct role in maintaining **alveolar patency**.
*Prevention of hypertension*
- **Hypertension** during intubation can be managed with specific medications like opioids or beta-blockers, or by optimizing anesthetic depth.
- Sellick's maneuver does not influence **blood pressure regulation**.
*Prevention of bradycardia*
- **Bradycardia** can occur during intubation due to vagal stimulation and is often managed with anticholinergic drugs like atropine.
- Sellick's maneuver does not affect **heart rate** directly.
